These are stress retings only, and functional operation of the device at these or any other conditions beyond those
indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for
extended periods may affect device reliability.
Maximum package power dissipation limits must be observed.
Temperature as possible.
If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents (
high driver currents (≥30mA), it may take up to 2.0 ㎲ for it to come out of saturation. This condition will shorten
the off time at frequencies 30kHz, and is magnified at high temperatures. This condition does not occur with a
Darlington configuration, since the output switch cannot saturate.
